Critical Situation

I accidentally delete all the Acronis images stored in the Acronis Image Zone if anybody does use Acronis, they should know it. However, somehow one of the drive has been assigned to Acronis C: which is free of use. The space of it is 14GB, divided from the drive consisted of 40GB. Another 26GB is for storage. However, this is what my friend does to me. Right now he has gone to Japan and then I have no one to rely on. I gotta do it by myself. Due to my stupidness and ignorance, I synchronized the 26GB with the Acronis Image Zone. After the synchronization, my 26GDB driver is gone. The driver of 26GB is assigned to be a J: Driver. And then I thought it would appear back after I delete the Acronis program. However, after the deletion, nothing happens. My question is whether it is possible to get rid of the Acronis C: and recover my J: drive. It seems I have stored a lot of things into it. Would you guys please help.
